Hi all, Got my rMBP in October 2012 and it's hasn't given me any trouble so far... Until now. It's not a bid deal, but it's started making a whirling sound, towards the top left of the keyboard, under the power button. I'm 99% sure that this wasn't making a sound previously, unless it was running hot, and the fans kicked in. Right now, the noise starts as soon as it's powered up. 1) Can anyone confirm that the rMBP is supposed to run quiet, and that I'm not going crazy? 2) Is there anything I can do to remedy this, or does it just need to go to back to Apple? Thanks for your help.
